| Abstract: | The dynamic performance of a small-scale MRC plant is important for its design and operations.A simulation model of LNG plant which consists of HYSYS cycle model and centrifugal compressor model was established.The dynamic performance of MRC plant under partial load was studied.The refrigerant flux hardly affected the load and the load should be adjusted by the compressor speed.The results also show that a refrigerant flux corresponding to maximum load and another refrigerant flux corresponding to high ener... |
